Remedial sealant for homes and businesses in Wellbrook
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have worktop sealant that has shrunk and split and wide, uneven beads that look worse than the old ones, we can help.
Around Wellbrook, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What affects the quote in Wellbrook
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the job
- Working hours on commercial sites
- Which sealant suits the joint
- The old material and how stubborn it is
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- Photos by email, if that’s easy
- Any previous sealing or DIY work
- The problem you’ve noticed
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.

What we are called out for in Wellbrook
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Common reasons people contact us are:
- Beads that never stuck properly
- Dark patches showing through the sealant
- Torn expansion joints
- A second bead peeling off the first
Letting a property close to Crowborough station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before you book anyone
- How the colour is chosen
- What product goes in the joint
- Who turns up on the day
- When the joint can take water or movement
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep the room well ventilated
- Keep an eye on the ceiling below the bathroom
- Ask why a joint failed before redoing it
- Deal with small splits early
Do not let anyone seal over it later. New silicone doesn’t bond to old.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Wellbrook, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
How to get a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Bathrooms and kitchens in Wellbrook
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
In the older streets around Church of St. Dunstan, walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as Mayfield Church of England Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Wellbrook, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
